Looking for a good Android 5.1 Lollipop ROM for your Galaxy S2 GT-i9100?
Check out the CM12.1S ROM, which is a hybrid of CM12S ROM from OnePlus One and latest Android 5.1.
This ROM features latest CyanogenMod CM12.1 Android 5.1 features along with OnePlus One camera, AudioFX, Screencast (screen recording app), and Hexo theme. I’ve tried many of the latest CM12.1 and Android 5.1/5.1.1 ROMs in the past week but found this ROM to be most stable with everything working out of the box except Netflix video playback. Also, if you want to know about all of the latest CM12.1 ROM features, check out this video.
